High-frequency Capacitance & Tan Delta testing presents unique challenges such as parasitic effects, signal integrity issues, and measurement drift. To ensure reliable and repeatable results, manufacturers must focus on proper impedance matching, temperature control, and effective data logging. Wrindu offers China-based OEM-grade testers, with firmware optimized for high-frequency regimes, ensuring accurate, high-quality measurements for manufacturers, wholesalers, and suppliers.
How do high-frequency conditions affect Capacitance & Tan Delta measurements?
High-frequency conditions introduce parasitic effects such as stray capacitances, lead inductance, and dielectric losses, which can distort Capacitance & Tan Delta readings. As frequency increases, phase accuracy and magnitude may drift. To minimize these effects, proper impedance matching and circuit layout are essential. Wrindu designs testers with calibrated frequency ranges, shielded probes, and optimized test fixtures to maintain accuracy even in high-frequency environments.
